Billionaire socialite bought Kim Kardashian's house and now they're partying together

Was there a “must be my best friend” clause when Marina Acton purchased Kim Kardashian and Kanye West’s mansion? The Keeping Up With the Kardashians star stepped out on Monday night to support the release of the billionaire socialite’s new single, “Fantasize.”

Also at the event were Chloe Green and Jeremy Meeks (aka “Hot Felon“).

Kardashian and Acton have been spotted together on a few occasions, going out to dinner at Craig’s after closing on the house and again over the holidays.

Acton purchased the Wests’ remolded Bel-Air home last year for $17.8 million. It’s clearly something she’s proud of — her Instagram page features a link in her profile directly to the Wall Street Journal story of the purchase. Acton said Kimye’s celebrity status had nothing to do with buying the mansion. Rather it was because she wanted to build a studio there, and she found it “inspiring.” She also told TMZ, “It’s an artistic house” and that she felt a good vibe there. “I love fashion, I love makeup [and] that’s Kim, I love music and singing, that’s Kanye,” she explained.
